Abstract: The invention relates to a device for the manufacture of stranded conductors by Roebel transposition of profile wires with a rectangular cross-section with a guide for the profile wires conveyed in two parallel stacks. The device is formed from side parallel guide surfaces and latches, which are offset through 90 DEG  with respect to said surfaces and one of which is provided per stack, the two latches being located diametrically opposite one another and being displaceable in parallel, in opposing directions, cyclically, and of slides which can move at right angles to the longitudinal extent of the stranded conductor for displacement in opposite directions of in each case one profile wire from a (lacuna) on the adjacent stack, while bending the profile wire. The slides are supported opposite one another in the other diagonal, in the same way as the triggers. The device furthermore comprises a control device for synchronisation of the cyclic operation of the drives for displacing the triggers and slides. The invention is characterised in that each slide (5) has allocated to it on the opposite side of the stranded conductor an opposing holder (8) which is offset with respect to the slide in the conveyance direction (9) of the stranded conductors and is supported displaceably in the opposite direction thereto, at right angles to the stranded conductors, and is driven in synchronism with the movement of the slides and triggers. <IMAGE>

Title: Solder alloys for semiconductor elements - contg. copper as well as aluminium and germanium for shorter soldering time at lower temp.
Inventor: ILLGEN LOTHAR DR
IPC: B23K35/02
Filed: 1990-06-27
Abstract: An improved solder alloy results from doping the usual Al-Ge solder (45-58% Al, 42-55% Ge) with small concns. of Cu. The alloy produced can be used either in strip form (added Cu up to 2%) or as a powder (added Cu up to 10%). The alloy is suitable for automatic operations in microelectronics and bonds at 450 deg C and contact times of 1 sec. or less. USE/ADVANTAGE - The prod. is useful for the automatic soldering of semiconducting transistors (chips) at lower contact times and temps. than conventional soldering compsns.. Improved wettability on the chip and substrate results from Cu addn.. In an example a solder alloy according to the invention was made by blending a solder of 55.5% Al and 44.5% Ge (100 pts. wt.) with Cu 1.60 pts. wt. to give a compsn. (wt.%) Al 54.97; Ge 43.93; and Cu 1.28. This was converted to strip by normal processes. It had a hardness of 86 MVm and could be reeled on to a mandrel of 20 mm dia.. During stamping the edges cut well and the strip is suitable for automatic soldering processes for chips at 450 deg C and a contact time of 1 sec.. The wettability on the chip was 70-80% and also 70-80% on the substrate (chemically polished Fe-Ni alloy) which is an improvement of some 25% as a result of the innovation.

Title: Optimisation of coercive strength of magnetic recording medium - based on cobalt and nickel, by incorporation of up to 3 atom per cent of oxygen during deposition
Inventor: GODA NORIYOSHI
IPC: G11B5/64
Filed: 1990-07-26
Abstract: The magnetic recording medium contains a metallic magnetic layer, with major constituents Co and Ni and at least one element selected from the Gps. IVA,VA and VIA of the Periodic System or Pt as an additive, features  an oxygen content of not more than 3.0 at.% relative to the total metal content. The medium contains the following parts: a non-magnetic substrate, an under-layer which contacts the substrate, an intermediate layer which contacts the under-layer, a metallic magnetic layer with an oxygen content and a protective layer. The substrate pref. consists of one of the materials Al, Al-alloys or glass, and has pref. an underlayer of Ni-P, which shows fine grooves. The intermediate layer is pref. Cr and the protective layer is C. The medium is pref. formed by deposition of the layers in succession on a heated substrate after the pressure in the vacuum chamber has been reduced to less than 5x10-7 Torr and an ambient has been established of Ar with an oxygen partial pressure between 0.001 and 0.1%. USE/ADVANTAGE - The incorporation of oxygen in the layer increases the coercitive strength and reduces the variability of this parameter within the range claimed (see fig.3). By using a very low vacuum before deposition the substrate can be fully degassed and the chamber does not contain excessive water and oxygen contamination. The medium formed has a high quality and stability.
